- ELECTRICAL COOKING- APPARATUS.

Application ill-ed April 16, 1924. Serial Io. 708.981.

Fig. 8 is a sectional viewtaken substan- 45 tially on the line 8-8 ofFigure 5. K Broadly stated,- my cooking a paratus comprises an elongatedframe inc-Fading a pair of spaced longitudinal bars supporting a set oftransversely arran ed heating or cooking plates, each indivi uallyoperable, and a batter tank positioned for movement longitudinally abovethe plates and adapted to deposit quantities of batter-upon any of theplates for cooking.

The main frame comprises a 7 pair of transverse end members 9, one beingof greater width than the other and arranged to support a receptacleover which the batter tank may be positioned when the apno paratus isnot being used, or when all of the plates are cooking cakes or the like.As shown in. Figure 6, the end members 9, comprise substantiallyinverted U-shaped castings having angular flanges 10 whereby oconnection to a back plate 11 is effected. This back plate preferablymounts. a mirror 12 or the like. A pair of vertically dis-- 4 posedlongitudinal bars 13 is arranged as shown in Figure 2, to connect thetwo end 70 This invention is an improved electrical cooking apparatushaving for an object to provide means whereby a rapid output of attercakes or the like may he obtained.

5 Another object is to provide an apparatus of this character having acooking surface and a batter tank arranged to deposit predeterminedquantities of batter upon the surface.

A further object is to provide a battery of plates having heating unitsso arranged as to be relatively independently operable.

A still further object is to provide a cook- 'n apparatus of thischaracter in which a hatter tank is movable above a set of cookingplates and includes means for accurately positioning the tank over anyone of the plates.

It is also an object to provide means for feeding a uniform quantity ofbatter at each operation.

Other objects will be in part obvious and in part ointed outhereinafter.

" In or er that the invention and its mode of operation may be readilyunderstood by persons skilled in the art, I have in the accompanyingillustrative drawings and in the following detailed descri tron basedmembers, said bars being secured to the end members by machine screws orthe like.

thereon set out one possible em odiment of These bars are transverselyspaced and the same. serve as supports for a set of heating or In thesedrawings: cooking plates 14 carrying de nding pins 75 Fig. 1 is a frontelevation of the cooking 15 fitting-in recesses 16 forme 1n the supaparatus. porting bar, these pins serving to center and 5 ig. 2 is an endview thereof. equi-distantly space the plates at all times Fig. 3,is afragmentary top plan view. even when expanded due to'the heating.

Fig. 4 is a sectional view taken substantially on a plane of line 4-4 ofFigure 3. F1g. 5 is a detail View of the devices for centering thebatter tank over each plate. 40 Fi "6 is a sectional view substantiallyontheline 6-6 of Figure 2. 1 Fi". 7 is a'detail 'YlGWOf the hangercarand y-the upper inner end. of the batter 8 2 A trackway is formedupon the forward so side of the frame for a purpose which will bepointed out- Thisltrackway consists in securing a pair of bars 17 uponthe for- :2 ward or front bar, forming a longitudinal channel infwhich'sup," orting elements car- 35 ried by a batter in are. positionedhriA hinged door or eaves; .1 8 .is nin1nted i 1pon the frontef tli'e'14. In Figure 2, current conducting wires 21 are shown and are adaptedfor connection to heating elements carried by the plates.

These plates each include an elongated body hollowed out to receive aheating element which is retained therein by a cover plate 22 mounting aterminal box 23 through which electrical connection is made.

As a means for assisting in the support of a slidable batter tank, apair of upper and lower verticall spaced guide and suporting rods 24 an25 is mounted upon the Back 11. The lower rod 25, as shown in Figures 1,5 and 8, is provided with spaced pairs of notches or recesses 26 whichseat spring actuated fingers or plungers 27 arranged in spaced brackets27' as shown n Figure 5. These brackets are attached to the lowerportionof the inner end wall ofthe tank. Through this arrangement ofplungers, means is provided to accurately center the batter tank over aplate upon which batter is to be deposited. As shown in Figure 7, theupper end of the tank T is provided with a bracket 28 arranged to mounta grooved wheel 29 which rests upon the upper rod 24, thus providing thesup porting means for the inner end of the tank.

In order that the outer end may be sunrted, I attach a bracket 30thereto the lh wer ends carrying a pair of spaced wheels or rollers 31fitting in the channel tracka. 's batter tank Tconsists of a main bodyportion or reservoir 32 having a set of depending longitudinally spacedmeasuring cups 33 formed integrally therewith and an 0 upper endclosable by means of a cover p ate 34. Each measuring cup has a closableoutlet 33 arranged to seat a valve 35 carried by a, rod 36 which extendsupwardly through the cover plate 34 and mounts a knob or the like 37.This valve is operable through the rod 36 by means of a lever i8 pivotedto a bracket 39 and carrying at its inner end a cross bar 40 providedwith bifurcated fingersor forks 41 which straddle the red as shown inFigure 4. In order to close the opening between the main tank body andthe measuring cu I provides valve 42 mounted upon the ower end of asleeve 43 whichis of suflicient diameter to permit backing uptherethrough of air from the cup 33 to insure complete filling andemptying of said cup. The upper end of the sleeve 43 is closed, anoutlet or return opening 44 ,being formed at a point below the coverplate so as to rmit excess batter to return to the tank an Y to allowair to esca e as before stated, This opening 44 a so allows air to enterwhen the cup is bein emptied and eliminates the tendency towar creatinga vacuum. Immediately above the closure for the sleeve is formed anopening 45 for the reception of a hooked finger 46 carried by a crossbar 47. This bar 47 is integrally formed and operable by a handie orlever portion 38 pivotally mounted upon the aforementioned bracket 39.This bracket 39 carries an integral handle 49 for co-act-ion with thelevers 38 and 48 to feed the batter from the .tank to the cooking plate.Handles 50 aremounted upon the sides of the tank to facilitate movementthereof along the trackway. As shown, the cover plate 34 is recessed ornotched to allow for positioning upon the body portion.

In using this apparatus a supply of batter is placed in the tank T andthe parts being positioned as shown in Figure 4, the lever 38 is moved,thereby raising the valve 42 and allowing the batter to fill themeasuring cup. ,As stated, the entire fillin and emptying of the cup 33is assured ue to the means heretofore described and shown to permitescape of air from the cup.

The valve 42 is then allowed to close and the tank '1 is shifted to aposition above the cooking plate to be used. The plungers 27automatically seat themselves in the recesses 26 and center the tankover the plate,

at which stage of operation the lever 48 is I ing cups 'itis understoodthat other numhere may be employed.

Mani estly, the construction shown is capable of considerablemodification and such modification as may fall within the scope of myclaims, I consider within the spirit of my invention.

I claim:

1. In a cooking apparatus, a batter tank having'an open upper end, ameasuring cup depending from t e tank bottom, filling and dischargecontrol valves for the cup, a hollow valve stem on the inlet valve 0ning through the valve into the cup, sai stem having an air openin nearits other end, a stem on the outlet va ve extending throu h the hollowstem and spaced from its wa. a cover plate having a slot receiving thevalve stems, a pair of superposed levers ivoted to one sideof the tankand res 'ly releasable connection between the levers and valve stem.

2. In a cooking apparatus, a batter tank havmgian open upper end, a setof integrally formed measuring cups depending ing into the cup throughsaidvalve and alined with said handle, loose separable connectionbetween the ends of the levers and 10 said valve stems, and a. slottedcover plate arrangeable over the open upper end of said tank.

In testimony whereof, I am: my signature.
